Profibus CP-342-5

Hallo,

I have a problem to wright a program tot communicate with a gateway connected to a profibus module CP-342-5.
The hardware configuration is ok.
I loaded de GSD file en i select for the geteway the type Anybus.
The adresses of the gateway are 16 word input (272-287) and 32 word output(272-287).
I think thad i can place the words in a DB for store the commands.

I have no idee wath i must use (function) to send and recieve al data of the DB to the profibus module.

Can anyone help me with a example or a explenation.

Thanks
Jacques

FC1 DP_SEND

The DP_SEND function (FC) transfers data to the PROFIBUS CP.

FC2 DP_RECV

The DP_RECV function (FC) receives data on PROFIBUS.

This came from Step 7 help file. Put these blocks into your program then press F1 for help on how to use each block.

Hope this helps

This should also help you.

If not I've got some text that I have written myself, in dutch, for using DP_SEND and DP_RECEIVE for Profibus.
